Customer:
The serial monitor shows no readable output. I’ve attached a screenshot showing a bootloop of around 6 seconds. I’m using the Inkplate_WiFi_HTTP_Request code example from your GitHub repository.

Soldered Support:
Change the baud rate for the serial monitor to 115200 bauds to get readable outputs.
Customer:
After changing to 115200 baud, here’s the output:
